Paradox will give your game the edge you need

If you’re into first-person shooters, you know how much of a difference a split-second can make. That’s usually the difference between fragging, and getting fragged. With the Paradox controller, you might just get the edge you need.

The Paradox looks like a standard PS2 controller with a trackball in place of the right analog stick. This is supposed to allow for finer control of your movements and faster input. Personally, I could never get used to the trackball, but I know plenty of people that swear by them.
